Operation Foxley
During World War II, Operation Foxley was a 1944 plan to assassinate Adolf Hitler, conceived by the British Special Operations Executive (SOE). Although detailed preparations were made, no attempt was made to carry out the plan. Historians believe the most likely date for an attempt would have been 13–14 July 1944, during one of Hitler's visits to the Berghof.

By then, he was considered by the British to be such a poor strategist that it was thought possible that candidates who would be in line to succeed him might present more of a challenge to the Allied war effort. Thornley also argued that Germany was almost defeated, and if Hitler was assassinated, he would become a martyr figure to some Germans and possibly give rise to a myth that Germany might have been victorious if he had not been killed by underhand means, leading to the threat of more wars with Germany in the future. As the Allied war aims had become not merely the military defeat of the Third Reich, but to destroy the National Socialist political ideology in Central Europe in general, this rendered the proposed operation potentially undesirable. The debate in the British government divided opinion, and so the operation was not authorised.
